Fatal AssertionError: Unhandled operation type: class GetAndTouchOperationImpl that leads to client death #262

Open GoogleCodeExporter opened 8 years ago

What version of the product are you using? On what operating system?
Spymemcached 2.8.1 on Ubuntu 12.04 LTS 64 talking to Couchbase sever 1.8.1. 
community edition
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

Tell me more...
From time to time we've got an exception:
Exception in thread "Memcached IO over {MemcachedConnection to 
Ubuntu-1204-precise-64-minimal/88.198.5.203:11210}" java.lang.AssertionError: 
Unhandled operation type: class 
net.spy.memcached.protocol.binary.GetAndTouchOperationImpl

    at net.spy.memcached.MemcachedConnection.handleIO(MemcachedConnection.java:260)
    at com.couchbase.client.CouchbaseConnection.run(CouchbaseConnection.java:229)

This breaks the main loop and leads essentially to client death (unable to 
perform any further operations):
java.lang.AssertionError: IO Thread is not running.

    at com.rutarget.couchbase.CouchbaseKeyValueStorageClient.getValueCAS(CouchbaseKeyValueStorageClient.java:183)

After looking at the code it seems found that it happens when retrying a failed 
‘get and touch’ operation.
